Is There Global Warming?
Welcome........
I am not a scientist and do not pretend to be. But, I have been watching the issue of climate change now for two decades and have found it is not what many say it is. Here are a collection of articles, sources, and information. Use it if you like. Hopefully it will encourage you to seek your own truth since this is one of the great issues of our time.

Massive increase in mining link
Sometimes a greener grid means a 40,000% increase in power prices link
$356 per kWh, storage charge link
State energy use by source link
In the EU renewable energy capacity is increasing yet CO2 emissions keep rising link
Burning wood is worse than coal link
The myth of the German renewable energy miracle link cosmic ray theory
Rooftop solar costs $800 per ton of CO2, where offsets only cost $10 link
Renewables 3% of global energy consumption link
Why battery back up is not practicle link
In the case of New York State, plans callfor the installation of 9,000 MW of offshore wind capacity by 2035 and 3,000 MW of battery storage by 2030. The wind system will likely cost in excess of $9 billion, and the battery system will likely cost about $7.5 billion. But this planned battery deployment is wholly inadequate to remove the wind intermittency.
If the wind system has an average output of 33% of its rated output, then the planned 3,000 MW of battery storage would only be able to deliver the average wind output for about two hours. To replace output for a full day when the wind isn’t blowing, 36,000 MW of storage would be needed at a cost of $90 billion, or about ten times as much as the wind system itself. Since several days without wind in most locations is common, even a day of battery backup is inadequate.
Imagine having a car that only runs 30% of the time, you would need a second car for when the first one won't operate. In addition, the 10-15 year lifetime of grid-scale batteries is no bargain. Wind and solar systems are rated for 20-25 years of service life. Traditional coal, natural gas, and nuclear systems last for 35 years or more.
Today, battery grid storage capacity is less than one millionth of national electricity output. Practical battery storage adds a cost factor of at least ten to the cost of the partner renewable system. It will be decades before battery storage plays a significant role in large-scale power systems, if ever.
$200,000 worth of Tesla batteries, which collectively weigh over 20,000 pounds, are needed to store the energy equivalent of one barrel of oil. A barrel of oil, meanwhile, weighs 300 pounds and can be stored in a $20 tank.
The annual output of Tesla’s Gigafactory, the world’s largest battery factory, could store three minutes’ worth of annual U.S. electricity demand. It would require 1,000 years of production to make enough batteries for two days’ worth of U.S. electricity demand. Meanwhile, 50–100 pounds of materials are mined, moved, and processed for every pound of battery produced. link
Mining link
However, what is beyond dispute is that eliminating fossil fuels and nuclear power would require literally millions of wind turbines, billions of solar panels, and several billion batteries like the half-ton power sources used in Tesla vehicles. This, in turn, would require a massive worldwide increase in mining for lithium, cobalt, copper, iron, aluminum, and numerous other raw materials.
Current mining operations to supply materials for today’s comparatively small amount of renewable power technology—plus batteries for laptop computers, smartphones, and electric cars—are already causing supply difficulties and serious problems for the environment. These mining operations are also imposing substantial harm on the men, women, and children who work in battery- and renewable energy-related mines, processing plants and factories in other countries.
As this paper shows, expanding mining on the scale needed to meet the renewable energy requirements contained in the Green New Deal and other proposed renewable energy mandates would cause unimaginable harm to the environment, wildlife, and humans.
The real cost of wind and solar. Wind and solar does not replace fossil fuel plants, spend up to 25 cents per kWh to save 2 cents of fossil fuel energy link
Reasons why renewables are not a complete solution link
Home batteries do not decrease CO2 emissions in most cases under current policies,a group of researchers from the University of California San Diego (UCSD) published a paper in Environmental Science and Technology reporting that there are very few cases in which operating a residential home battery reduces overall emissions—assuming that households are economically rational and trying to minimize costs.. Of course, if the battery is only discharged during periods of peak emissions and only charged when fossil fuel use is low, then a household might reduce emissions. But across 16 representative regions, operating a battery this way ended up being costly Link
